IS THERE AN AMP? ARE YOU SURE YOU HAVE DECK/ AMP HOOKED UP TO A CONSTANT "KEY ON" POWER SOURCE? I WOULD GET A TEST LIGHT(REAL CHEAP AT WALMART, OR AUTOPARTS STORES) AND SEE IF MAIN WIRE IS NOT A TIMED KEY ON CIRCUT.... ALSO IF AMP IS BEING USED MAKE SURE ITS HOOKED TO REMOTE ON WIRE(USUALLY BLUE WIRE) AND NOT POWER ANTENNA LEAD OR SOME OTHER TEMP/TIMED POWER LEAD. GOOD LUCK

The wire to which you refer applies power to the radio with the ignition switch in the ACC position and also maintains power flow to the memory when the radio is off. The proper connection should be apparaent from the installation instructions that came with your Metra adapter.

hi this sounds like you have connected the permanent live wire to an auxiliary wire, ie, what ever the power source you have connected it to, only works until the vehicle has started, then the power is stopped, sorta like.. say, the starter motor, it only uses the power when it is needed then when it is running it shuts the power off, just like the lights on the dash ect ect, your best bet would be to find a permanent live from the battery supply...hope this helps

YOU CAN JUST GO TO BEST BUY, PC RICHARDS ETC.. AND YOU CAN BUY A PLUG KIT THAT WOULD FIT YOUR YEAR MODEL OF YOUR CAR AND IT WOULD CONNECT TO YOUR AFTERMARKET STEREO JUST MAKE SURE YOU HAVE THE MODEL NUMBER (STEREO) BUT IF YOU WANT TO WIRE IT YOUR SELF THE LIVE WIRE IS YELLOW THE ACC WIRE IS RED AND YOUR GROUND IS BLACK ONCE YOU ISOLATE THESE WIRES THE REST ARE SPEAKER WIRES. I RECOMMEND BUYING THE KIT ITS ALOT EASIER PLUG AND PLAY.

What you have been told is correct, these proprietary systems are great for the manufacturer, but when they start to have issues (and they will) they leave you 2 options: pay through the nose to stay original or replace the amps with new ones....the upside of this is aftermarket amps are soooo mugh better than stock that it is lauhgable.
